Following last year’s success, we are co-locating the 4th Human Computation Workshop with AAAI 2012 in Toronto, Canada.

Human Computation is the study of systems where humans perform a major part of the computation or are an integral part of the overall computational system. Over the past few years, we have observed a proliferation of related workshops, new courses, and tutorials, scattered across many conferences. In this 4th Human Computation Workshop (HCOMP 2012), we hope to draw together participants across disciplines -- machine learning, mechanism and market design, information retrieval, decision-theoretic planning, optimization, human computer interaction -- for a stimulating full-day workshop at AAAI in the vibrant metropolitan Toronto this summer. There will be presentation of new works, lively discussions, poster and demo sessions, and invited talks. We welcome early work, and particularly encourage submission of visionary position papers that are more forward looking, and perspectives from a variety of disciplines outside of the core AI community. There will be presentation of new works, lively discussions, poster and demo sessions, and invited talks. We hope to see you there!
